Question

find the (a) mean, (b) median, (c) mode, and (d) mid - range for the data and then (e) answer the given question. listed below are foot lengths in inches of randomly selected women in a study of a countrys military in 1988. are the statistics representative of the current population of all women in that countrys military? 9.0 8.6 10.4 8.6 10.3 9.3 9.4 9.8 10.1 10.4 10.4 a. find the mean. the mean is 9.66 inch(es). (type an integer or a decimal rounded to two decimal places as needed.) b. find the median. the median is 9.8 inch(es). (type an integer or a decimal. do not round.) c. find the mode. select the correct choice below and, if necessary, fill in the answer box to complete your choice. a. the mode(s) is(are) inch(es). (type an integer or a decimal. do not round. use a comma to separate answers as needed.) b. there is no mode.

Explanation:

Step1: Recall mode definition

The mode is the value that appears most frequently in a data - set.

Step2: Count frequencies

The data set is 9.0, 8.6, 10.4, 8.6, 10.3, 9.3, 9.4, 9.8, 10.1, 10.4, 10.4.
The frequency of 8.6 is 2, the frequency of 9.0 is 1, the frequency of 9.3 is 1, the frequency of 9.4 is 1, the frequency of 9.8 is 1, the frequency of 10.1 is 1, the frequency of 10.3 is 1, and the frequency of 10.4 is 3.
Since 10.4 appears the most number of times.

Answer:

A. The mode(s) is(are) 10.4 inch(es)
